Electromechanical System for the Functional Evaluation of Muscular Activity during the Active Movement in the Elbow Joint

Mexico Electromechanical system includes a graphic user interface to select loads and display target trajectories. Time response of electromechanicsl system was simulated with a Feedforward + PD controller. Elbow muscles response, kinetic variables and time required to perform measurements were examined in 3 healthy adults during the active elbow movement at 2 loads and compared to a pulley machine. Measurement time of the electromechanical system was reduced to 57.29%; the angular velocity was similar in both systems; the brachioradialis muscle response in the electromechanical system was different for flexion and extension. The results indicate that the electromechanical system accomplish the objectives, but it is suggested to implement a feedback controller with disturbance handling as the simulated.
